Stan Greenberg, the pollster who aided Bill Clinton's run to the White House in 1992, said he was far more confident about Barack Obama's chances than he was for the last Democratic president 16 years ago. "Everything that I saw has solidified," he said of recent polling. "Every poll that I saw of Obama I looked and said, 'I feel more and more confident.' And I'm beginning to look forward to his presidency. I've never had an election where I worried less about the outcome."
